Reddit reviews Japan: A Documentary History: v. 1: The Dawn of History to the Late Eighteenth Century: A Documentary History

I actually think Ieyasu is interesting in his own right, not just for setting in motion one of the largest times of national peace in the history of modern civilization (like since 1 AD), but because of his life story and how he was willing to sacrifice everything for his goal, which he saw as larger than himself.

Hideyoshi was interesting in his own right; rising from the ranks of sandal-bearer to Shogun, and then realizing that, in order to keep his power, he has to stop other people from doing what he did, and so creates a class system. Even in his infamous sword-hunt, he used much of the metal to build a giant Buddha statue, which appeased the peasants he was simultaneously oppressing.

However, I think Hideyoshi was a bit unstable as a leader and his leadership would have never led to lasting peace, e.g. those invasions of Korea.

p.s. If you are looking for translations from those times, I might recommend the books from my Japanese Politics Through the Ages class. Here is the first one It's not actually translations of personal writings of any of the leaders, but it's all the legal and political decrees and proclamations through the ages, and so is a fantastic Primary Source collection.

p.p.s. i think Nioh's interpretation of Tokugawa as a character is really cool. Not only does it match the attitude that I've grown to know from the writings about him, but the portrayal has a feeling of a real badass who knows exactly what he is doing.
